nwfilter: convert the gentech driver code to use virNWFilterBindingDefPtr
Reviewed-by: Laine Stump <laine@redhat.com>

Now that the virNWFilterBinding APIs are using the nwfilter
update lock directly, there is no need for the virt drivers
to do it themselves.
Reviewed-by: Laine Stump <laine@redhat.com>
Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
The nwfilter update lock is historically acquired by the virt
drivers in order to achieve serialization between nwfilter
define/undefine, and instantiation/teardown of filters.
When running in the modular daemons, however, the mutex that
the virt drivers are locking is in a completely different
process from the mutex that the nwfilter driver is locking.
Serialization is lost and thus call from the virt driver to
virNWFilterBindingCreateXML can deadlock with a concurrent
call to the virNWFilterDefineXML method.
The solution is surprisingly easy, the update lock simply
needs acquiring in the virNWFilterBindingCreateXML method
and virNWFilterBindingUndefine method instead of in the
virt drivers.
The only semantic difference here is that when a virtual
machine has multiple NICs, the instantiation and teardown
of filters is no longer serialized for the whole VM, but
rather for each NIC. This should not be a problem since
the virt drivers already need to cope with tearing down
a partially created VM where only some of the NICs are
setup.

Plenty of projects switch from FUSE to FUSE3. This commit enables
libvirt to compile with newer fuse-3.1 which allows users to have
just one fuse package on their systems, allows us to set
O_CLOEXEC on the fuse session FD. In general, FUSE3 offers more
features, but apparently we don't need them right now. There is a
rewrite guide at [1] but I've took most inspiration from sshfs
[2].

If an app within a container wishes to read from /proc/meminfo
from a different position than the beginning of the file, we can
have FUSE keep track of all the lseek()-s and reflect them in
@offset argument of read callback (lxcProcRead()). This is done
by setting fuse_file_info::nonseekable. If we don't do this, then
FUSE reports errors back the app that does lseek().

When mounting a FUSE it is possible to bypass kernel cache by
specifying -odirect_io mount option. This is what we currently
do. However, FUSEv3 has a different approach - the open callback
(lxcProcOpen() in our case) can set direct_io member of
fuse_file_info struct. This results in the same behaviour, but
also works with both FUSEv1 and FUSEv3. The latter does not have
the mount option and uses per file approach.

The idea behind lxcProcReadMeminfo() is that we read the host's
/proc/meminfo and copy it line by line producing the content for
container, changing only those lines we need. Thus, when a
process inside container opens the file and lseek()-s to a
different position (or reads the content in small chunks), we
mirror the seek in host's /proc/meminfo. But this doesn't work
really. We are not guaranteed to end up aligned on the beginning
of new line. It's better if we construct the new content and then
mimic seeking in it.

The way that vircgroupmock works is that the vircgrouptest
creates a temporary directory and sets LIBVIRT_FAKE_ROOT_DIR env
variable which is then checked by the mock at the beginning of
basically every function it overrides (access(), stat in all its
flavours, mkdir(), etc.). The mock then creates a CGroup dir
structure. But the test is allowed to change the directory, to
accommodate environment for the particular test case. This is
done by changing the environment variable which is then detected
by the mock and the whole process repeats.
However, the way the mock detect changes is buggy. After it got
the environment variable it compares it to the last known value
(global variable @fakerootdir) and if they don't match the last
known value is set to point to the new value. Problem is that the
result of getenv() is assigned to the @fakerootdir directly.
Therefore, @fakerootdir points somewhere into the buffer of
environment variables. In turn, when the test sets new value (via
g_setenv()) it may be placed at the very same position in the env
var buffer and thus the mock fails to detect the change.
The solution is to keep our private copy of the value (by
g_strdup()) which makes the variable not rely on
getenv()/setenv() placing values at random positions.
